Hi All,
Oracle 8.1.6
I have 2 tables which have been analyzed. The query takes about 30+ seconds
to run. If I run it many times it is faster as data gets loaded into
buffer
cache. I want to optimize when that is not the case. All the fields in the
query have a separate index created EXCEPT for
ACCRUED_AND_PAID.hold_payment_flag.
Phy_Contracts has 10,466 rows.
Accrued_and_Paid has 820,919 rows.
Here is output from explain plan
SELECT STATEMENT Cost = 1382
SORT AGGREGATE
NESTED LOOPS
TABLE ACCESS BY INDEX ROWID PHY_CONTRACTS
INDEX RANGE SCAN PCON_CMPY_FK
TABLE ACCESS BY INDEX ROWID ACCRUED_AND_PAID
INDEX RANGE SCAN ADPD_PCON_FK
Any ideas what I can do to speed this query.
SELECT COUNT(a.phy_contract_id)
FROM accrued_and_paid a, phy_contracts b
WHERE a.hold_payment_flag = 'Y'
AND b.phy_contract_id = a.phy_contract_id
AND b.company_id = 16
AND b.contract_type = 'IC';
List of single column index on PHY_CONTRACTS
INDEX_NAME COLUMN_NAME
------------------------------ ---------------------
PCON_CONTRACT_TYPE_IDX CONTRACT_TYPE
PCON_CMPY_FK COMPANY_ID
PCON_PK PHY_CONTRACT_ID
List of single column index on ACCRUED_AND_PAID
INDEX_NAME COLUMN_NAME
------------------------------ ------------------
ADPD_PCON_FK PHY_CONTRACT_ID
Thanks
Rick
